Project History
FormDr
https://formdr.com/A healthcare app for doctors to send and receive HIPAA-compliant online forms. I made their app ready for production, added Stripe integration for billing, and built a visual drag-and-drop form builder for them. Within the first few months, the app received hundreds of submissions.
Screen Box
A macOS app saves certain apps on your screen and lets you restore them later. I conceptualized, designed, and built it from scratch. I worked on top of their feedback with some active users.
In a Bottle
An Android app to leave digital messages in specific locations and find messages left by others near the current location. I developed the idea, designed it, and built the app, using native Android technology and Parse as the back-end service to store the data.
EmprestAê
A marketplace for renting, lending, and borrowing everyday items from people around you. I assembled the team during a Startup Weekend event, and we built a website and an Android app for college students.
Emotion.me
Android app for the wedding management startup Emotion.me. The app allows existing users to manage their to-do list, photos, gift list, and guest list and find suppliers for different aspects of a wedding.
Umwho
Developed an Android app for the Umwho startup. The app allows for exchanging contact information over Bluetooth to make meeting people nearby easier. The client had an iOS app, and I built the Android version of it.
SmartCards
SmartCards is a to-do list iOS app with an assistant that guides the user to complete extra information about each task, like due dates or reminders. Developed using Swift, Parse, and Reactive Programming.
